LIQUID-GAGE.

Specification of Letters Patent. Patented Dec, 28, .1920

Application filed February 7, 1920. Serial No. 356,829.

will be readily applicable for use; to produce a device as characterized which is com paratively more practical and which is thoroughly eflicient and reliably effectual in use; to provide a device which embodies an inclosed actuating flexible element which is arranged between an indicating means and a float mechanism, and a novel and simple means for permitting the proper operation 01 said actuating flexible element by preventing the buckling thereofand eliminating lost motion and to thus obtain accuracy as one of the features of this device; to produce a device which is complete initseli and which embodies a tank filling cap which is operatively connected or correlated with a particular part of the device which part supports the float mechanism intended for arrangement within a tank containing the liquid to be gaged. With these and other objects in view the invention resides in the particular provision and arrangement of parts hereinafter more fully described and illustrated in the accompanying drawings,

, in which Figure 1 is a view illustrating the invention and its application to use.

Fig. 2 is a side elevation of the float mechanism and the parts correlated therewith.

Fig. 3 is a detail view illustrating the manner in which the filling cap is turnably related with a part of the device.

Fig. 4: is a transverse sectional view taken through the indicator and the line %4; of Fi 1.

flig. 5 is an enlarged detail view of the means for preventing the buckling of the actuating element.

One of the uses to which this invention may be put is to gage the quantity of gasolene within the supply tank of an automobile and wherein the indicator forming a the instrument board of'the automobile. It 1s to be understoodhowever, that this device may be put to other uses; This device 18 particularly useful upon automobiles and part of the device will be arranged upon devices can be made complete to include tank filling caps of different and special sizes to fit to diflerent and special tanks so as to be readily applicable for. use'and-without requiring expensive alterations and changes to parts to which it is applied. The

float mechanism forming a part of the de:

vice will be correlatedwith the filling cap. f and the-disposition of the float mechanism within the tank containing the gasolene without being affected by such things as at its point of'connection withthe bracket i 11. I Thisfilling cap is provided with the usual threaded flange and sismade of a standard size tofit the filling opening of a standard size tank. 'The float mechanism 16 g i is supported by the bracketll andconsists of spaced guide members 17 which are 3ro-" vided from a single piece ofimaterial. he guide members are attached to the plates 12 ofthe bracket 11. A float 18 is arranged for movement on the guide members 17 and this float has pivotally connected thereto, as at 19, an arm 20, which has jointed connection, as at 21, to an arm 22, which is pivoted as at 23, between the plates 12 of the a bracket 11.

Indicating means 24- are provided which are actuated through the rise and fall of the float 18 through the intervention of an actuating flexible element between the arm 22 and an indicator forming a part of the indicating means. The indicating means 21 consists of a case 25 which is so constructed as to properly support a sight panel 26 which is disposed in front of the 'indicia plate 27.

This plate 27 is provided with elongated slots 28 in which the pointers 29 carried by 1 thepointer bar 30 move. The indicia plate 27 embodies certain intelligentmatter with inclosed by a close wound flegrible tubular member 34: one end thereof being connected to the end of the tubular member 10 and theopposite end thereof is connected to the case 25. A convolute member 35 is secured to the arm 22, and encircles the end of the wire 31 attached tofthe arm 22 to prevent buckling of; the wire 31 as the arm 22 moves to and fro to thus eliminate lost motion and giving to the device highest degree ofaccuracy. ss-a: gag

Erom the foregoing it Will also be manifest that the indicatingmeans is ofsimple construction and one, easytoread because of the plurality: of indicating points; that;the arrangementof the j ointedlevers of the float mechanism is such that at no time will they assume; positions. to prevent the upward movement of the float, but on the contrary, the float-Will be readily movable at all times, being easily started, since the guide membersi17, as; joined atthe bottom, limit the downward movement of the float; thatthe tan-k fillingicap is turnably correlated with parts of, the device to permit the complete device to be readily assembled and to remain in a set: position while the cap is being screwed in'place; that only a small opening is requiredin. the dash orinstrument board asithe'jcasemaybe for the indicating means.

WVhat isr-claimed as new is:-..

1'. A, liquid gage. comprising, means responsive tothe riseand fall oftanked liquid, a tank and closure cap turnably related to said means and adapted to, support said means so, that=the said means maybe disposed Within the tank containing theiliquicl, and; indicating. means operable by the first mentioned means and adapted toibe ar ranged at a point remote from said first mentioned means.

2. A liquid gage comprising, indicating means, means including a tubular member, bracket secured to said member, float mechanism suspended from said bracket, which mechanism is responsiveto rise and fall of liquid, an inclosed flexible element operatively connected between the indicating means and said float mechanism, and a tank filling cap turnably connected to said tubular member.

3. A liquid gage comprising, indicating means, means including a curved tubular member, a tank filling cap turnably connected tosaid member, float mechanism supported by said member including jointed arms, one of which arms is pivotally mounted, a convolute member-secured to the pivotedarm, and an inclosed flexible element operatively correlated, with the indicating means and the float mechanism, the said element having an end thereof extending through said convolute member and secured o said pi ot d rm.

LA liquid gage comprising, indicating means, including a curved tubular member, tank filling cap turnably connected to said member, float mechanism supported by said ,inember including jointed arms, one ofwhich arms is pivotallymounted, a curved convolute member secured to the pivoted arm, and an inclosed flexible element operatively correlated With the indicating means and the float mechanism, the said element; having an end thereof extending through said convolute member andsecured to said pivoted arm, the said curved convolute member being disposed so as to have the free end thereof move in said tubular member.

Intestimony whereof We have affixed our signatures.
